Abstract: A circuit breaker with at least one disconnect mechanism and a smart monitoring system implements nuanced fault logic in order to minimize disruption to operation of the circuit breaker under a fault condition, and enables the circuit breaker to address nuisance or low severity faults separately from load switching. Under low severity or nuisance fault conditions, the smart monitoring system temporarily disconnects affected loads from the power supply rather than tripping the entire circuit breaker so that the loads can be reconnected to the power supply if the fault condition resolves within a short amount of time. In addition, the disconnect mechanism(s) that are used to temporarily disconnect the load(s) are configured to be re-closed after opening without requiring manual intervention. In high severity fault conditions, the smart monitoring system actuates tripping of the entire breaker, requiring manual re-closing of the circuit breaker.
